The only real failure in life is not to be true to the best one knows.

Failure is instructive. The person who really thinks learns quite as much from his failures as from his successes.

Success is not final, failure is not fatal: it is the courage to continue that counts.

If you're not failing every now and again, it's a sign you're not doing anything very innovative.

Every adversity, every failure, every heartache carries with it the seed on an equal or greater benefit.

I think success has no rules, but you can learn a great deal from failure.

It is not a disgrace to fail. Failing is one of the greatest arts in the world.

It's not a very high failure rate if you choose people that you really like the sound of.

Failure is unimportant. It takes courage to make a fool of yourself.

Don't be afraid of missing opportunities. Behind every failure is an opportunity somebody wishes they had missed.
